"Never choose your friends over your family or a boyfriend or girlfriend over the family," she said. "My mom has always taught us that blood is thicker than water. No one will ever understand the dynamic of your family. Ever. We are the closest family ever and we are the most insane family ever."

Moretz has been an open supporter of gay rights in the past. Back in March, ahead of the Supreme Court's hearings on same-sex marriage, the actress posted a photo of a red equal sign to her Twitter account in support of equality.

Moretz's "Kick-Ass 2" is currently in theaters, and she will also star in the remake of the 1976 horror classic "Carrie," which premieres next month.
